WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 750,663, datedJanuary26, 1904.

- 7 Application filed August 29, 1903. SerialNo. 171,211. (No model.)

To all whom, it vea concern:

Be it known that I, SAMUEL LENZNER, a citizen of the United States,residing at Detroit,

in the county of \Vayne and State of Michigan, have invented certain newand useful Improvements in Weather-Strips, of which the following is aspecification, reference being had thereinto the accompanying drawings.

The invention relates to weather-strips more particularly designed foruse on car-windows, but also applicable to house-windows and for otherpurposes.

It is the object of the invention .to' obtain a construction in which atight joint is maintained, while at thesame time the sash has a limitedfreedom to move laterally. This will permit the sash to be moved freelyand will also prevent rattling.

The invention consists in the peculiar construction of the strip. and,further, in the peculiar construction and arrangement of said strip inrelation to the sash and window-frame, as hereinafter set forth.

In the drawings, Figure 1 is a sectional perspective view illustratingthe improved strip applied to a single-sash window, such as a car-.

window. Fig. 2 is a horizontal section therethrough. Fig. 3 is a similarhorizontal section through a double-sash window.

A is a window-frame, which may be of any suitettlble construction exceptas hereinafter set fort B is a window-sash slidingly secured in saidframe by stops, such as C and D. As shown in Fig. 1, the stop C bearsagainst the inner face of the sash B, and the stop D is arrangedadjacent to but spaced from the outer face of the sash, so as to permitof a limited lateral movement of the sash between stops. The sash B isalso preferably of such a width as to provide suitable clearance betweenits edges and the window-frame.

E is the weather-strip. This in the form shown consists of a metallicstrip which is bent to form a substantially rectangular corner a and apair of wings 6, extending obliquel y from said corner portion. Thesewings terminate in flanges 0, extending in planes substantiallyparallel, respectively, with the planes of the corner portions a. Thesash B is formed with a shouldered bearing, preferably by rabbeting outa portion thereof, as at (Z. This forms an angle or corner complementaryto the corner a of the strip. The rabbet is located in such relation tothe stop D that when the strip E is placed to engage the corner (4 withthe bearing-pl the flanges 0 will embracesaid stop, bearingagainst theperpendicular faces thereof. The wings I) of the strip are of such aproportion that when said strip is thus engaged the sashB will bepressed against the stop 0 and will also be centered between the sidesof the windowframe.

With theconstruction described the stop D will normally hold the sashcentrally within the frame and braced against. the stop (I; but byreason of the fact that the strip is formed of resilient metal thepressure in both directions is yielding. This will permit of readilyraising or lowering the sash in the frame, while at all timesmaintaining a tight joint.

In Fig. 3 is shown a modification illustrating a double-sash window, inwhich E is a second strip similar in construction to the strip E. Thisstrip is arranged in relation to the parting-strip F of the window-frameand the second sash B, the arrangement being the same as in theconstruction already described.

While I have shown a specific form of strip, I believe that variousmodifications in shape may be made without departing from the spirit ofmy invention.

The essential feature is a construction in which the bearing portion ofthe strip is maintained in contact with a shouldered bearing on the sashand also with a bearing on the Window frame or stop. while theintermediate portion is yielding and resilient.

As shown in the drawings, the strip E is arranged on the outside of thewindow-sash and normally presses said sash inward against the stop C.Furthermore, the inclination of the portion 1) and the stop forms abeveled edge, which permits dust or cinders to be deflected instead ofbeing lodged in the joint.

The construction just described is especially advantageous forcar-windows, and it has a further advantage that the yielding pressureof the strip against the sash will cause the latter to frictionallyengage the stop C, and thus the window may be held in raised positionwithout the necessity of a locking device. The pressure of the springdoes not interfere with the free raising or lowering of the sash, forthe reason that the spring being on the outside the operator may easilypress against the sash sufiiciently to relieve it from frictionalcontact with the stop.

Another advantage of the construction is that the strips may be appliedto windows without any change in the windowframe. All that is necessaryis to remove the sash and form the rabbet therein for engagement withthe strip. Again, strips of this character may be removed and replacedwithout taking out the sash.

What I claim as my invention is 1. The combination with a window-frame,of a slidable sash associated therewith, a re silient strip bent backupon itself and abutting a portion of the sash, the respective arms ofwhich yieldably engage an angle bearing on the frame.

2. The combination with a window-frame having a longitudinal stopthereon, of a sash within said frame having a bearing portion, and aresilient strip abutting said nearing portion and havinglaterally-projecting portions arranged to engage respectively one sideand edge of said stop to yieldably center the sash within said frame.

3. The combination with a window-frame,

of a sash within the same, having a bearing portion, a resilient stripbent back upon itself, the bent portion resting in said bearing portion,and its arms loosely engaging respectively one side and edge oftheframe.

4. The combination with a window-frame, and a stop thereon, of a sashslidable within said frame, and a strip for yieldingly holding said sashagainst the stop, said strip having a return-bentcross-section with theangle thereof engaging with the bearing on the sash, and the edgesyieldably embracing an angle bearing on the frame.

5. A weather-strip comprising a resilient strip of return-bentcross-section, forming a central angle portion separated portionsextending from said angle portion, and edge portions substantiallyparallel respectively with the opposite sides of said angle portion.

6. The combination with a window-frame having stops thereon, of a sashslidable between said stops, and 'rabbeted on one side to form aclearance from one stop, and a strip of return-bent cross-section havingits bent edge engaging an angle of said rabbet, and the edges of itsseparate sides respectively engaging the stop and side of the adjacentstop.

7. The combination with a window-frame and slidable sash, of a stop onthe frame inside of the sash, and a resilient strip on the outside ofthe sash, yieldingly pressing thereon and having laterally-projectingarms yieldingly engaging a side and edge of said frame to form aweather-tight joint, and also a frictional engagement between the sashand stop.

8. The combination with a window-frame,

of a slidable sash, a stop on said frame inside the sash, and aresilient strip yieldingly pressing against the outer face of said sash,and inclined in relation thereto, a portion of said strip extending overthe outer edge of said frame whereby dust is deflected and preventedfrom lodging in the joint.

In testimony whereof I aflix my signature in presence of two witnesses.
